Jennifer Lopez Has A Major Musical Malfunction At Huge Los Angeles Gig!

She’s so embarrassed as the music went out during her performance of ‘On The Floor!’

This wouldn’t fly on American Idol!

Jennifer Lopez, 41, channelled Ashlee Simpson‘s infamous Saturday Night Live meltdown during a performance of her hit song ‘On The Floor’ — the music went out and she was left going through the motions without vocals!

J. Lo – the total pro played it cool however during the May 14 Wango Tango concert in Los Angeles at the Staples Center, looking fierce the whole time and addressing the audience when her mic came back on, at about 2:11 on our video.

“Nobody keeps mama down,” she told the adoring crowd. “This is what show business is all about, baby. Who’s getting fired tonight? Somebody’s getting fired tonight!

Then once the sound came back on she played a flawless, high-energy version of the song from the top.
